peerd is a new experimental browser extension for Chrome and Firefox that functions as an AI agent, enabling users to automate tasks directly within their existing browser sessions.

Key Points

• Operates as a native browser agent that reads pages, drives interactions, and executes code in sandboxed environments like Linux VMs and JS Notebooks.
• Employs a "bring your own key" (BYOK) model, storing API credentials in an encrypted local vault that never transmits secrets to cloud servers.
• Utilizes hardened browser security features, including V8 isolates and WebAuthn, to ensure the agent cannot access raw page data or run untrusted code.
• Features a modular architecture consisting of five core components: provider adapters, egress security, execution engines, runtime logic, and a peer-to-peer dweb layer.
• Currently in an experimental 0.x beta phase, requiring users to manage API keys for services like Anthropic, OpenRouter, or local Ollama instances.

Why it Matters

By running entirely within the browser, peerd offers a privacy-focused alternative to cloud-based AI automation tools that typically require external data processing. This architecture allows users to maintain control over their sensitive API keys and browsing data while leveraging AI to perform complex, multi-step web tasks.
